Filed: 1986-09-09
Abstract: PURPOSE:To entirely and uniformly wash a surface by reducing the turbulent flow in the lateral direction of washing water being ejected, by making the cross-sectional shape of vortex stream forming cavity part communicating with a washing water jet orifice similar to that of the washing water jet orifice. CONSTITUTION:The high pressure washing water supplied to a vortex stream forming cavity part 7 through a nozzle case is ejected from a washing water jet orifice and a vortex stream is formed in the washing water, which flows in a divided state by a drain edge 8, in the vicinity of the jet orifice 6 by the water stream flowing out from the jet orifice.

In this case, since the cross-sectional shape of the vortex stream forming cavity part 7 communicating with the jet orifice 6 of the nozzle is similar to that of the jet orifice 6, the turbulent flow in the surface direction of the jet orifice 6 is suppressed and the washing eater can be ejected while accurately regulated to a desired jet pattern.
